PERSONAL INJURY OR DEATH, THE FOLLOWING BULLET POINTS MUST
BE OBSERVED WHEN INSTALLING THE UNIT
IMPORTANT NOTE: Remove wood shipping rails prior to
installation of the unit. See important note under Roof Curb
Installation Only.
.
,
ALL INSTALLATIONS:
I
MPORTANT NOTE: Unit should be energized 24 hours prior
to compressor start up to ensure crankcase heater has
sufficiently warmed the compressors. Compressor damage may occur if this step is not followed.
NOTE: Appliance is shipped from factory for vertical duct
application.
Proper installation of the unit ensures trouble-free operation.
Improper installation can result in problems ranging from
noisy operation to property or equipment damages, dangerous conditions that could result in injury or personal property
damage and could void the warranty . Give this booklet to the
user and explain it’s provisions. The user should retain these
instructions for future reference.
• For proper operation and condensate drainage, the
unit must be mounted level.
• The flue outlet hood must be at least three feet above
any forced air inlet located within ten feet. The
economizer/manual fresh air intake/motorized fresh
air intake and combustion air inlet mounted on the
unit are not affected by this restriction.
• Do not locate the unit in an area where the outdoor
air (i.e. combustion air for the unit) will be frequently
contaminated by compounds containing chlorine or
fluorine. Common sources of such compounds include
swimming pool chemicals and chlorine bleaches, paint
stripper, adhesives, p aints, varnishes, sealers, waxes
(which are not yet dried) and solvents used during
construction and remodeling. V arious commercial and
industrial processes may also be sources of chlorine/
fluorine compounds.
• To avoid possible illness or death of the building
occupants, do NOT locate outside air intake device
(economizer, manual fresh air intake, motorized fresh
air intake) too close to an exhaust outlet, gas vent
termination, or plumbing vent outlet. For specific
distances required, consult local codes.
• Allow minimum clearances from the enclosure for fire
protection, proper operation, and service access (see
Unit Clearances). These clearances must be
permanently maintained.
• When the unit is heating, the temperature of the return
air entering the unit must be between 50°F and 100°F .
GROUND LEVEL INSTALLATIONS ONLY:
• When the unit is installed on the ground adjacent to
the building, a level concrete (or equal) base is
recommended. Prepare a base that is 3” larger than
the package unit footprint and a minimum of 3” thick.
• The base should also be located where no runoff of
water from higher ground can collect in the unit.
ROOF TOP INSTALLATIONS ONLY:
• T o avoid possible property damage or personal injury ,
the roof must have sufficient structural strength to carry
the weight of the unit(s) and snow or water loads as
required by local codes. Consult a structural engineer
to determine the weight capabilities of the roof.
• The unit may be installed directly on wood floors or
on Class A, Class B, or Class C roof covering material.
• To avoid possible personal injury, a safe, flat surface
for service personnel should be provided.
• As indicated on the unit’s data plate, a minimum
clearance of 36” to any combustible material is
required on the access side of the unit. All combustible
materials must be kept out of this area.
• This 36” clearance must also be maintained to insure
proper combustion air flow. The combustion air intake
must not be blocked for any reason, including
blockage by snow.
• Adequate clearances from the unit to any adjacent
public walkways, adjacent buildings, building openings
or openable windows must be maintained in
accordance with National Codes.
UNIT PRECAUTIONS
• Do not stand or walk on the unit.
• Except for holes in the wiring entrances (see Figure
below), do not drill holes anywhere in panels or in
the base frame of the unit. Unit access panels
provide structural support.
ELECTRICAL ENTRANCE LOCATIONS
• Do not remove any access panels until unit has been
installed on roof curb or field supplied structure.
• Do not roll unit across finished roof without prior
approval of owner or architect.
